I have used the Biomatrica DNA storage system for plasmids and bacterial genomic DNA. Yes, it is very over-priced, but it also works well enough. There have been some decent studies that show it is an improvement over desiccated naked DNA or -80C storage.
Another option is FTA paper (Whatman). These are just chemically-treated paper cards. One can apply naked DNA in solution or whole cells to the paper and then recover enough DNA for transformation or PCR. http://www.whatman.com/FTANucleicAcidCollectionStorageandPurification.aspx
There has been a lot more research on FTA paper because it is such a cheap and stable medium. It is still on patent, but not for long.
The patent is informative. http://patft.uspto.gov/netacgi/nph-Parser?Sect2=PTO1&Sect2=HITOFF&p=1&u=/netahtml/PTO/search-bool.html&r=1&f=G&l=50&d=PALL&RefSrch=yes&Query=PN/5496562

Hello colleagues,please, does anyone have any experience with the commercial DNA capsule services, like DNAcapsule.com or securigene.com?Are their methods of DNA preservation sound? Isn't it just snake oil?I am very tempted to use them for DNA archiving because they don't require constant freezing, but I'm not sure whether the companies really provide what they say. Would I be able to find a difference if they sent me back a vial of salt water in iron case?I will be glad for any opinion.Best regards,Jiri Dluhos
